弹丸破片速度衰减规律研究

Velocity Attenuation Regularity of Projectile Fragments

采用理论分析和试验测试相结合的方法,对弹丸破片的速度衰减规律进行了研究.通过理论分析得到计算弹丸破片迎风面积的数学模型,由试验得到某型远程杀伤弹破片的质量分布情况和初速分布情况,通过数值分析,用Matlab绘出了该弹破片速度衰减曲线.结果表明,初速和飞散距离相同的破片,破片质量越大,存速越大.该方法对于计算弹丸杀伤半径和杀伤面积有实际意义.

By combining theory analysis with test measurement, the velocity attenuation regularity of projectile fragments was discussed. Through theory analysis, the mathematical model for calculating the frontal wind area of projectile fragments was achieved. The mass and the initial velocity distribution situations were obtained based on the experiment of certain long-range fragmentation projectile. The velocity attenuation curve of fragments was drawn by Matlab. The result shows that the larger the fragment mass is, the higher the remaining velocity is under the conditions of equal initial velocity and the same dispersing distance. The method has reality significance on calculating projectile kill radius and area.
